Benefits of technology

[0053]One or more further aspects pertains to a wound dressing which is constructed to accelerate the wound-healing process. According to an additional optional aspect, the wound dressing can be constructed such that it retains its wound-healing properties for an extended period of time, and thus does not have to be changed as frequently as conventionally-constructed wound dressings. According to another aspect, the wound dressing can possess increased effectiveness in preventing infection.
[0054]In some cases, the wound dressing can be provided with a combination of additives which, when provided in a wound dressing according to the teachings contained herein serve to increase the effectiveness of the wound dressing to promote healing relative to conventionally-constructed wound dressing materials containing conventional antimicrobial agents. In further cases, the wound dressing can be provided which generally contains a higher degree of antimicrobial agent, such as PHMB, than is typically contained in comparable wound dressings. Through specific wound dressing constructions and targeted and/or controlled release of antimicrobial and other agents, the wound dressing can increase its effectiveness

Problems solved by technology

A related problem is that of the incidence of bacterial infection of post operative and other wounds.
Such infections not only increase the demands on the resources of our healthcare system through lengthened hospital stays, but also require treatment with antibiotics.
Due to the misuse of antibio

Example

[0074]FIGS. 1-2 may be referred to in order to facilitate the following discussion. A wound dressing 10 can be generally formed from one or more discrete layers (e.g., 20, 30, 40). When composed of multiple layers, the dressing 10 includes at least one interior layer 30 as well as one or more exterior layer(s) 20, 40. The exterior layer(s) being characterized by at least one surface 20a adapted for contact with the surface of the skin of a wearer, or a wound bed, and an opposing surface 20b contacting an interior layer, or at least one surface 40a facing away from the surface of the skin or wound bed and exposed to the surrounding environment as well as an opposing surface 40b contacting an interior layer. The interior layer(s) 30 lack either a surface for contact with the skin surface or wound bed, or which is both exposed to the external environment and in contact with an interior layer.

[0075]While the illustrated embodiment includes one interior layer 30 and two exterior layers 2...

Abstract

A wound dressing includes one or more layers containing an antimicrobial agent and optionally at least one of: a chelating agent, a second antimicrobial agent, a zinc-containing agent, a cell-signaling agent, and an additional active ingredient or agent.

Description

BACKGROUND[0001]1. Field[0002]The present disclosure relates to multilayer wound dressings containing an antimicrobial agent, a sponge formed from such a dressing, and methods of fabricating such dressings and sponge.[0003]2. Related Art[0004]One common technique for reducing the cost of providing health care services is to reduce the amount of time of in-patient hospital stays, and to reduce to a minimum the amount of person-to-person interaction between a patient and healthcare professionals. A related problem is that of the incidence of bacterial infection of post operative and other wounds. Such infections not only increase the demands on the resources of our healthcare system through lengthened hospital stays, but also require treatment with antibiotics. Due to the misuse of antibiotics, finding an effective treatment for such infections can prove difficult. Moreover, tremendous resources are needed to constantly develop new antibiotics to replace other such drugs that have bee...
